Making Gold Green: New Nontoxic Method for Mining Gold
May 14, 2013
Northwestern University scientists have struck gold in the laboratory. They have discovered an inexpensive and environmentally benign method that uses simple cornstarch--instead of cyanide--to isolate gold from raw materials in a selective manner. This green method extracts gold from crude sources and leaves behind other metals that are often found mixed together with the crude gold.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2014, its budget is $7.2 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
